What is a hard lump under the buttocks?

If a hard lump appears under the skin of the buttocks, it is generally a buttocks mass, which is mainly caused by a lipoma formed by subcutaneous fat. Among lipomas, fibrous tissue tumors are more common, also known as sebaceous adenomas. Most of these tumors are benign tumors. If you want to get a thorough treatment, it is best to remove them through surgery, which is also the best treatment method.

Clinical manifestations

Fibroma can occur in various parts of the body, of varying sizes, located under the skin or in the muscle layer, grows slowly, has a smooth surface, a hard texture, and can move freely. If it is a neurofibroma, it is mostly distributed along the nerve trunk and may cause radiating pain when touched.

Lipomas can also occur in various parts of the body. They vary in size and grow slowly, often becoming very large. The surface of the skin is smooth, the color does not change, the edges are clear, and they are soft to the touch. Psoralea often occurs on the face, behind the ears, back or buttocks. It can be single or multiple, round or oval in shape, with clear boundaries, thinner skin in the central part, and often a small blue dot in the center that adheres to the skin. When pyroma is combined with infection, the local area will be red, swollen, hot and painful.

Prevention tips

Fibroids are mostly benign tumors, and if they are completely removed, there is generally no recurrence. In order to differentiate it from other diseases clinically, surgical resection and histopathological examination are generally recommended. The subcutaneous fibroma in the midline of the posterior neck can be felt when the head is tilted back, but cannot be felt when the head is lowered (because it is covered by the tense posterior cervical fascia).

It is more common in the elderly and generally does not require surgery. In addition, some muscle diseases, such as sternocleidomastoid muscle nodules in children with torticollis, sclerofibroma of the rectus abdominis in women, and sclerosing myositis, can also be felt as lumps under the skin. But it does not come from the subcutaneous connective tissue. The main difference between this type of lump and fibroma is that the lump is often connected to the muscle (which can be identified by palpation).

Etiology and pathogenesis

Traditional Chinese medicine believes that the occurrence of such diseases is related to spleen and lung dysfunction. In the metabolism of water, the lung qi fails to spread and descend, the spleen qi fails to transport and transform, the phlegm and dampness evil accumulate in the meridians, the menstrual qi stagnates, the Ying and Wei are out of harmony, the phlegm and dampness accumulate for a long time and form nuclei, which appear on the skin surface and cause subcutaneous tumors.
